Something so simple. Yet, so true. Yes, it takes time. Yes, an introvert would need to leave the safety of their comfort zone. Making a human connection. I care. You matter. Need to work up to top of the ladder. See full and worthy post from The Chief Happiness Officer:

“Please do not underestimate the effect of something as simple as saying good morning at work. Studies show that when you have a good start to your work day, you’ll typically have a good day. Here’s our easiest and best tip for kicking your work day off with happiness: The Level 5 Good Morning. We call it that because there are several approaches to saying good morning at work:

Level 0: You ignore people completely

Level 1: A somewhat unintelligible grunt

Level 2: Saying good morning without looking at people

Level 3: Make eye contact as you say good morning

Level 4: Also say something more than just good morning, e.g. “How are you?” or something more personal.

Level 5: Also touch the other person – e.g. a handshake or a pat on the shoulder.

At what level are the typical good mornings in your workplace? And what would happen if you took it to level 5?”
